With the development of society, many family houses and hotel kitchens will use ventilation ducts. Therefore, the installation of ventilation ducts in Jinan is very important. Once unreasonable, it will cause a bad taste phenomenon, which will affect the home life. The unreasonable design and installation of kitchen smoke exhaust pipes often result in unobstructed kitchen smoke exhaust, which directly affects the use of lampblack purifiers. The main reasons are as follows:

　　關于通風管道出現排煙不暢通的原因和解決辦法是什么?下面由通風管道廠家的人員介紹一下：

　　What are the reasons and solutions for the obstruction of smoke exhaust in ventilation ducts? The following is an introduction by the professionals of ventilation duct manufacturers.

　　就是設計不合理：因在開業裝修時預計的就餐人員飽和值低于現今就餐飽和值，后廚工作量增加，多臺灶同時作業，原設計風機轉數低，排煙量小，導致排煙不暢。解決方法：在排煙口加裝風扇式四葉或六葉排煙風機，提高排煙量，或更換大風量風機;

　　First of all, the design is unreasonable: because the expected saturation value of dining staff is lower than the current saturation value, the workload of the back kitchen is increased, multiple stoves are working at the same time, the original design of fan speed is low, smoke exhaust volume is small, resulting in poor smoke exhaust. Solution: install fan-type four-leaf or six-leaf smoke exhaust fans at the smoke outlet to increase smoke exhaust volume or replace large-volume fans;

　　再有就是設備陳舊老化：部分廚房設備中的老式排油煙設備排油煙罩老化，導致煙罩漏風，排煙量降低。排煙風機老化導致轉速降低，排煙量降低，老式排油煙設備的油煙管道都比較細(管徑約300mm*300mm),因長時間積存油垢又不方便清洗，也同樣導致排煙效果不好。

　　Then there is the aging of old equipment: part of the kitchen equipment in the old exhaust fume equipment exhaust hood aging, leading to the leakage of smoke hood, reduce the amount of smoke exhaust. The aging of exhaust fan results in the decrease of rotational speed and exhaust smoke volume. Old exhaust fume equipment has thin pipelines (about 300 mm*300 mm in diameter). Because of the accumulation of grease scale for a long time and inconvenient cleaning, the exhaust smoke effect is also not good.

　　后一點就是特別重要的是要加強平時通風管道保養和清洗工作。

　　Finally, it is particularly important to strengthen the maintenance and cleaning of ventilation pipes in peacetime.
